Launch Your Own Nanosatellite Into Space
First time accepted submitter Rozine writes "Ever wanted to launch your own satellite into space? Thanks to a project at the Cornell Space Science Lab, now you can. In the words of the grad student leading the project, Zac Manchester, 'What better way of showing off your uber-geek credentials than having your own spacecraft?' Zac hopes that by shrinking the size of each spacecraft and using advancements in computer and solar cell technology, satellites can follow the path of the personal computer revolution, opening up space for the masses. For small donations you will receive mementos, but for $300 and up you will get your very own satellite to be launched into space. Perfect for slashdotters and school projects everywhere!" We covered this project in its infancy back in July. I'm glad to see it gained traction.
Pretty much what sibling said. These creatures will likely be launched into very low Earth orbit, and will likely hit re-entry in less than a couple months at most. A "nanosatellite" won't have any attitude control, or any fuel for that matter. It won't have the means to alter whatever orbit (and subsequent decay) it may get kicked off into.
Quo usque tandem abutere, Nimbus, patientia nostra?
They are aiming for an orbit time of a few days to a few weeks until they reenter and burn up upon reentry. They are doing that specifically so they don't leave any space junk.
RTFA.
You are entitled to your own opinions, not your own facts.
that was my first thought. the last thing we need is thousands of geeks launching their own space junk.
If you had clicked on the link...
"Because we will only launch KickSat into a low-altitude orbit, we can guarantee that all of the Sprites will re-enter the Earth’s atmosphere within a few days or weeks, leaving no trace of space debris. KickSat itself will last somewhat longer, but should burn up in the atmosphere within a few months."
You make it sound like for 300 bucks, you should get your own shark in space, with a frickin' laser on it no less!

I don't know how flexible (if at all) the parameters are for your very own "chip" sized satellite but wouldn't it be possible to make it survive re-entry? If it were made of ceramic and light (not dense) enough, couldn't it be designed to "gently" de-orbit without building up the heat that would cause it to vaporize.
Shape might be important too, I understand how that the first space capsule designers were initially flumoxed be the inability of their needle nosed re-entry vehicles to survive more than a few seconds in the hypersonic wind tunnels before melting. Then, a clue from nature in the form of Tektites; spherical blobs of glass of extraterrestrial origin that managed to survive due to the shock wave that protected them. (Russian re-entry vehicles were spherical for a time, now I think they, like the Americans, are using blunt cones). So if they can't be flat, maybe you'll have to take the space of a few "chip" sized satellites to send one golf-ball sized satellite capable of re-entry.
What a scoop that would be if you could do this! Imagine a worldwide competition for "find the space golf ball" where the person who finds the (hopefully) intact ceramic ball will get a reward and fame. (There could be a code inside to verify the winner, or perhaps DeBeers would sponsor putting a nice diamond in it). If constructed properly, it could be made to float so a water landing wouldn't automatically lose it. Maybe some sort of retro-reflector could be used to make finding it easier as well (but would restrict the likely recovery teams to professionals).
Actually since the chance of finding one old be so small, I'd imagine you'd have to send up a bunch with the first one found getting the big reward. Still finding any of them would be a great collectors item! Finally there might be some (very small) uses for being able to return (very small) samples from space but because of the difficulty in finding it, it's probably best suited for some sort of game or promotional event.
Attitude control is what I like to see engineered, not merely just in our nanosatellites, but pretty much in all our tech devices.

Hey, has anybody mentioned the Space Junk problem yet?
